Leakages from underground storage tanks (UST) at an operational petrol filling station located in a densely populated urban area in Northern Italy, resulted in significant TPH and BTEX contamination (with concentrations up to 1,000 μg/L and 100 μg/L respectively), impacting the soil and groundwater.
Contamination was migrating off-site and presenting an unacceptable risk to off-site receptors, resulting in a remediation requirement to reduce contaminant levels to below 350 μg/L TPH and 1 μg/L BTEX.
The application design for the 65m2 target area comprises of
8 injection points arranged in a 3 x 3 m grid spacing, which is being carried out over 2 phases. The first phase consists of the injection of RegenOx (oxidiser); the second of a further dose of RegenOx, followed by ORC-Advanced.
